JAMES F. WINCHELL, OF SPRINGFIELD, OHIO, ASSIGNOR OF ONE-FOURTH TO EMIL BAUROTH, OF SAME PLACE.

HAY-TEDDER.

SPECIFICATION forming part of Letters Patent No. 322,878, dated July 21, 1885.

Application filed March 26, 1884.

To all whom it may concern.-

Be it known that I, JAMES F. WINoHELL,a citizen of the United States, resident at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Hay-Tedders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a vertical sectional View of my device. Fig. 2 is also a similar View.

This invention has relation to improvements in machines for stirring up and turning over hay in order that it may dry quickly; and the invention consists in the construction and novel arrangement of devices,as will be hereinafter more fully set forth,and pointed out in the claims appended.

In the accompanying drawings, the letter A designates the wheels of the tedder, and B the axle,to which is attached a tilting frame, 0, extending in front and in rear of the axle. D represents the shafts, which in the construction illustrated are pivoted to bearings E, secured to the axle. The front end of the tilting frame 0 is connected to the shafts by a link, F, which is pivoted to the arm G of the lever H, which is pivoted to a fulcrum-bearing, K, on the shafts.

L indicates a rotary-crank shaft on the tilting frame,having an end pinion, P, which engages an annular toothed plate or gear N on the drive-wheel.

J J represent the fork-arms, carrying at their lower ends the forks V. The fork-arms are connected to the cranks of the shaft L by pivoted rods Z. Joints are employed in making the connections between the rods Z and the fork'arms, as indicated at I. The connecting-rod Z of each fork-arm extends from the central part of said bar at such an angle that the thrust of the rod will be nearly at right angles to the fork-arm. The lower portion of (No model.)

the fork-arm is, however, designed to close toward the connecting-rod when the fork strikes an obstruction, springing out again to the limit of the joint when the fork has become disengaged from the obstruction. In on der to produce this effect the extensions (1 or upper portions of the fork-arms are provided with springs S, which connect them to the rods Z with sufficient firmness to hold the fork-bar in rigid relation with the said arms at the joint I during the work or scattering the hay, as the resistance of the hay is not sufficient to overcome the tension of the springs.

The outer ends of the rods Z are provided with stop-lugs a, which are designed to engage a lateral projection, 12, on the fork-arms, for the purpose of attaining rigidity at the joint I, as before stated.

It will be observed that the lug prevents the upper portion of the fork-arm from turning forward toward the rod Z, and that said rod is inclined slightly. The break of the joint is therefore upward, and the construction is such that although the joint will stand the normal action of the fork in its work upon the hay without yielding, yet when an obstruction is encountered by the fork the joint will yield promptly and the upward movement of the fork-arm will be quick and effective in releas- I ing the fork from the obstruction.

Rods R connect the upper ends of the forkarms to the forward portion of the tilting frame by pivoted connections 0.

The stem (1 of the seat bis secured to the portion 6 of the tilting frame which is in front of the axle, in order to facilitate the operation of depressing the front of said frame by the weight of the driver when the lever H is disengaged from the rack-arch or holder 9 and pulled toward the said driver. The forks of this tedder are positively connected to the lower ends of the fork-arms, no springs or other yielding devices being employed at the points of connection. The forks therefore are always firm and do their work in an effective manner.

When a fork strikes a stone or other small obstruction, the joint on the rod Z yields, so that the fork is raised as the machine progresses, and clears the obstruction. Should a fork strike a stump, the joint will yield at once, and the fork will be quickly raised, as the machine goes forward, to the top of the stump, clearing the same.

If a fork should in its movement descend vertically upon the top of a stump, the joint will promptly yield, and as the machine moves forward the fork will escape from the top of the stump without injury.

I do not desire to confine this invention to the precise construction herein shown, as it may be varied easily by' those skilled in the art of constructing machines of this character.

It will be readily perceived that the invention involves the employment of a rising forkarm or fork-carrier, a joint-connection with the crank, and a spring acting in opposition to the joint as essential features.

Having described this invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a hay-tedder, the combination, with the fork-arm, of the link which is pivoted at one end to the fork-arm by a joint adapted to arrest the movement of the fork in one direction only, and at the other endpivoted to the operating-crank, substantially as specified.

2. In a hay-tedder, the combination, with an operating-crank and fork-carrying arm, of the connecting-rod Z, having a joint adapted to arrest the movement of the fork in one direction only, a spring operating to hold the joint down, and a connecting-link pivoted to the upper end of the fork-carrying arm and attached to the forward part of the frame, substantially as specified.

3. The combination, with the fork-arm J, of the pivoted rod Z, connected to an operatingcrank, its joint I, having a stop-lug, and the spring connecting said rod to the upper portion of the fork-bar, substantially as specified.

4. In a hay-tedder, the combination, with a fork-carrying arm, of a joint-connection with the link, which is adapted to arrest the movement of the arm in one direction only, and said link connecting the arm with the crank, and a spring acting in opposition to thejoint to hold the fork-carrier in a yielding manner so as to permit the fork-carrier to rise in meeting an obstruction, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
